Reading from esp 32 projects book it says to try the “CameraWebServer” example. Tried to compile code. Got 3 errors:

1. exec: “python”: executable file not found in $path
   Error compiling for board TTGO T1
   I have python 2.7 and python 3 installed on my system.
   Why does the compiler not find one of my pythons?

Hi Paul.
Did you add Python to PATH when you installed Python?
If not, I adivse you to uninstall Python and install it again. But don’t forget to add it to PATH.

Go to python.org/download and download Python.

Open the downloaded file to start the Python installation wizard.

The following window shows up.

IMPORTANT: Make sure you check the option Add Python to PATH. Then, you can click on the Install Now button.

When the installation is successful you’ll get the following message.

You can click the Close button.

Then, try compiling the code again.

Regards,
Sara

Or just add the location of your Python executable to your PATH – https://geek-university.com/python/add-python-to-the-windows-path/
